4. Write the difference between if and if else statement.
Ans. The if statement is the simplest conditional statement. Here, a statement or a collection of statements
within the if block are executed only if a certain condition or expression evaluates to True. Whereas, The
if-else statement executes different blocks of code based on whether a condition is true or false.
5. What are Iterative statements?
Ans. AI can analyze images, videos, and speech to find patterns of manipulation. It uses machine learning to
identify unnatural edits or changes, helping verify if the content is real or fake.

Skills
1. A school wants to use AI to monitor student participation in online classes. What step of the AI project cycle
should they begin with and why?
Ans. They should begin with Problem Scoping to clearly define the issue—such as low student engagement—
and understand the stakeholders (teachers, students, school management) before planning the solution.
2. A food delivery company wants to predict delivery times based on location, weather, and traffic. Which type
of problem is this—deterministic or probabilistic? Justify your answer.
Ans. This is a probabilistic problem because the outcome (delivery time) depends on changing conditions like
traffic and weather, which cannot be predicted with complete certainty.

3. SmartClass AI is an edtech company aiming to improve online learning experiences for schools. They plan to
develop an AI-powered system that tracks student engagement during virtual classes using webcam analysis,
including eye movement and posture. The goal is to provide teachers with insights into student focus and
participation levels in real time. Create a 4W Canvas for this problem.
Ans.

Question Answer
Who Who are the stakeholders? SmartClass AI, teachers, school management,
students
What What is the problem? Teachers are unable to monitor student attention
and focus during online classes, which affects
learning outcomes.
Where What is the context/situation in which the In online classes where students are learning
stakeholders experience the problem? remotely and teachers have no way to know if
students are paying attention or are distracted.
Why What would be of key value to the Real-time monitoring of student attention will help
stakeholders? teachers adjust teaching strategies and improve
learning outcomes.
How will the solution improve their It will allow teachers to identify students who need
situation? support, increase participation, and make online
learning more effective and personalized.
